Fluroxypyr (4-amino-3,5-dichloro-6-fluoro-2-pyridyloxyacetic acid) is a widely used herbicide sprayed on crops worldwide. The effects of fluroxypyr maize growth and the soil microbial community structure have not been reported. In this study, impacts bacterial in endophytes rhizospheric/non-rhizospheric soils were evaluated. We found that structures non-rhizospheric rhizospheric similar. alpha diversity showed richness endophytic communities mature roots was reduced after application. No...
High density carbon (HDC) ablator is one of the promising candidates toward thermonuclear ignition in inertial confinement fusion (ICF), but it shows largest ablation front instability growth as compared to other traditional materials. In this Letter, we propose a novel HDC-CH capsule design, opening way mitigate hydrodynamic instabilities by using CH outermost layer, while keeping HDC main for maintaining advantage short laser pulses. The layer completely ablated during shock transit phase....
The Hohlraum physics experiments performed on the SGIII-prototype laser facility are simulated by using our two-dimensional radiation hydrodynamic code LARED-H, and influence of intensity simulations is studied. Both temporal temperature x-ray spectrum from agree well with observations, except that M-band fraction (greater than 2 keV) obviously smaller observation. According to study, coupling efficiency around 70% for Hohlraums.
Direct-drive is one of the key approaches in study inertial confinement fusion, but laser imprinting caused by intensity inhomogeneities main obstacles to achieving ignition direct-drive. It has previously been demonstrated that a thin high-Z overcoat on side target can significantly mitigate (S P Obenschain et al 2002 Phys. Plasmas 9 2234). In current work, 1D multi-group radiation hydrodynamic code RDMG, coupled with detailed configuration accounting non-LTE atomic physics package MBDCA...
We coupled the one-dimensional multi-group radiation hydrodynamic code RDMG with MBDCA atomic physics package, which uses Matrix-Block Method to solve rate equations of Detailed Configuration Accounting (DCA) non-LTE model, and applied RDMG-MBDCA different flux limiters fe simulate a laser-irradiated CH-tamped Au disk experiment at SGII laser facility. From our simulations, we found that higher leads faster ablation, earlier x-ray breakout time maximum flux, an spectrum intensity. However,...
Low density and low convergence implosion occurs in the exploding-pusher target experiment, generates neutrons isotropically to develop a high yield platform. In order validate performance of ShenGuang (SG) laser facility test nuclear diagnostics, all 48-beam lasers with an on-target energy 48 kJ were firstly used drive room-temperature, DT gas-filled glass targets. The optimization has been carried out optimal uniformity was obtained by combination beam repointing target. final irradiation...
The National Ignition Facility successfully achieved target gain 2.4 thus marginally entering into burn stage.Meanwhile, a recent conceptual design on 10 MJ laser driver [Matter Radiat. Extremes 9, 043002 (2024)] provides new room for exploring novel designs and interesting phenomena in burning plasma after ignition. In this paper, we propose an amplifier scheme with extended stage, which includes secondary implosion, generates extremely hot dense fusion fireball, produces additional gain....
Fusion ignition has been successfully achieved at the National Ignition Facility, but main obstacles of low-mode asymmetries, laser-plasma instabilities (LPIs), and hydrodynamic (HIs) still remain in path toward a predictable yield for fusion ignition, especially high gain. A recently proposed octahedral spherical Hohlraum, i.e., Hohlraum with six laser entrance holes symmetry [Lan et al., Phys. Plasmas 21, 010704 (2014); Rev. Lett. 127, 245001 (2021)], was demonstrated to have advantages...
Thinner silicon substrate are expected to be used in solar cells for cost reduction. In this contribution, we numerically discussed a series antireflection structure light confinement design that may applied with thin substrates. The results show nano-pillar-array nitride coating has very low reflectance over the whole response region of cells. average could reach 2.34%, which is fundamentally coincident reported experimental results. Planar reflection at back surface cell was investigated...
Some of our recent studies on hohlraum physics are presented, mainly including simulation study experiments SGIII prototype, the design Au + U sandwich for ignition target, and an initial elliptical pertinent drive laser power in order to generate radiation profile.
In this study, experiments and simulations of Ne-like Ge soft X-ray lasers driven by nanosecond fundamental-frequency (1ω) double-frequency (2ω) are performed. The results show that 2ω also able to drive produce lasers, even though the requirements for driving conditions greatly increase compared 1ω lasers. It is expected laser outputs at 23.2 23.6 nm will be stronger higher power densities. provide a good foundation executing using existing large facilities, which cannot currently sustain
